STATE PATENT HEATER FOR USE IN MANUFACTURE OF ARTIFICIAL FUEL.

SPECIFICATION forming part of Letters Patent No. 535,182, dated March 5, 1895.

Application filed March 5,1894- Serial No. 502,338. (No model.)

To all whom it may concern:

Be it known that I, HERMAN S. ALBRECHT, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Heaters for Use in the Manufacture of Artificial Fuel, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has for its object the heating of disintegrated coal and other combustible products before said disintegrated coal, &c., is compressed into cakes and tablets as desired for use.

A further object of my invention is to provide means for the heating of such fuel, and at the same time incorporate said disintegrated fuel with a suitable preparation.

A further object of my invention is to provide means for the heating of disintegrated coal, &c., and incorporate a suitable compound with said disintegrated fuel and discharge said disintegrated fuel into a chute leading to compression rollers.

To the above purposes my invention consists in certain new and novel features of construction that will be hereinafter described and claimed.

In order that my invention may be more fully understood, I will now proceed to describe it, reference being had to the accompanying drawings, in which- Figure 1 is a side view of my complete apparatus, the forward portion of same being broken away to more clearly illustrate the device. Fig.2 is a front elevation of my apparatus. Fig. 3 is a cross-sectional view on the line 3-3 of Fig. 1, looking in the direction of the arrows a. Fig. 4 is a vertical cross-sectional view through a central portion of a modified form of my drier. Fig. 5 is a longitudinal sectional view of a T- joint attached to a supply pipe, and a nozzle within said T-joint to form a jet of steam.

Similar numerals refer to similar parts throughout the several views.

The apparatus here shown. is constructed in three sections, said sections being numbored respectively 1, 2 and 3. These are similarly constructed, being composed of the pairs of side-plates 4 and 5, 6 and 7 and 8 and 9, which are bolted to the top plates 10, 11 and The sections 1 and 3 have the for- The other ends of these sections 1 and 3 are bolted to the ends of the central section 2, thereby forming practically an inverted box like structure. The lower edges of these sections 1, 2 and 3 are provided with outwardly extending flanges 17. Acentral partition or plate 18 is securely bolted to these flanges l7, and a rectangular box like structure, composed of the sections 19, 20 and 21 provided with outwardly extending flanges 22, is bolted to the under side of this central partition or plate 18. The section 21 is provided with a rear wall 23 and a front wall 24, which is similar in construction to the front of a boiler furnace, being provided with the furnace doors 25 and the ash or draft doors 26. Thus it will be seen how a rectangular centrally partitioned box like structure is formed.

Extending rearwardly from the front plate 24 and immediately below the central partition or plate 18, is a series of grate-bars 27, the rear ends of which rest on the bridgewall 28. 1

An opening 29 is formed in the rear part of the side-wall of the lower section 2i, and discharges into a smoke-stack or flue 30.

The top plate 12 of the section 3 is provided with a like aperture and discharges into a pipe 31, whichin turn, connects with the flue 30 immediately above the drier. A discharge chute 32 is located at the rear of the section 3 and immediately above the partition or plate 18, and discharges onto the compression rollers 33.

An inlet chute 34 from the disintegrator is provided at the front end of the plates 10 in the section 1, and discharges into the charm ber 35.

Interior walls 36 and 37, provided with flanges 38, are bolted to the top plate 10, 11 and 12, and to the central partition or plate 18, and extend the entire length of the drier, thus forming air spaces 39, which may, if de sired, be filled with asbestos, or other non-heat conducting material.

Journal-boxes 40 are located in the sidewalls of the upper sections 1, 2 and 3, and are for the reception of horizontally extending 60, which leads from atank 61.

right angles to the pipe 49 and securely held shafts 41, which have rigidly mounted thereon pairs of sprocket-wheels 42. These sprocketwheels 42 carry sprocket-chains 43, which are provided with the longitudinal extending plates of sheet metal 44, thus forming an endless carrier within the chamber 35. This endless carrier always moves in the direction of the arrow A.

The shaft 45 in the rear section 3 projects slightly beyond the side-Wall 9, and has rigidly secured thereto a sprocket wheel 46, over which travels the drive-chain 47, thus imparting motion to the entire endless conveyer.

Located in the front plate 15, and opening into the chamber 35 immediately below the disintegrator chute 34 is the T-shaped casting 48. The forward end of this casting 48 is turned slightly upward, for the purpose that will be hereinafter shown.- Held to this T- shaped casting 48 by means of screw-threads and extending upwardly,is a short section of pipe 49, to the upper end of which is secured the coupling 50. To the upper end of the coupling 50 is secured a section of pipe 51, which in turn is provided with a joint 52, section of pipe 53, valve 54, joint 55, and pipe Running at to the coupling 50, are a pipe 62, valve 63, pipe 64, coupling 65, and an upwardly extending pipe 66 which discharges from the tank 67.

Extending into the open end of the T casting 48 is a pipe 68 provided with a cut-off valve 69. This pipe 68 leads from the steamsupply.

The upper plates 10, 11 and 12 are provided with the removable sections 70, which are immediately above the sprocketwheels 42. By these removable sections the interior of the chamber 35 may be cleaned, and the boxes 40 in which the shafts 41 carrying the sprocketwheels 42, may be oiled.

A thermometer 71 is located in the sidewall of the section 2, the bulb of which must necessarily be located within the chamber 35. In Fig. 4 l have shown a modified form of my drier. This form is constructed in every way as the one just described, with the exception that an auxiliary bottom 72 is bolted to the longitudinally extending bars 73, said bars 73 lying immediately upon the partition plate 18 and adjacent the inner side-walls 36 and 37. Thus it will be seen a chamber 74 is formed. This chamber 74 is for the reception of hot air, steam, superheated steam, &c. A supply pipe suitably located supplies said chamber with such steam, &c. Within the tank 61 is held a suitable solution of tar, pitch, or asphaltum. Within the tank 67 is held a suitable solution of brine.

The numeral 75 designates the disintegrator, from which the chute 34 discharges into the chamber 35.

The operation of my drier is as follows: When disintegrated coal, or other combustible material is fed through the chute 34 to the interior of the chamber 35, the valve 63 is closed, and the valves 54 and 69 opened. The pipe 68 being connected with the steam supply will necessarily cause a jet of steam to issue from the nozzle located within the T-shaped casting 48. The solution within the tank 61 flowing through the several pipes and into the T-shaped casting 48, will, by reason of the steamjet issuing from the nozzle, be thoroughly separated or divided, and together with the steam be driven or thrown against the disintegrated coal, or other material, as it falls from the chute 34 into the chamber 35. By reason of the forward end of the T-shaped casting being turned slightly upward, the s0- lution together with the steam, will travel in the direction of the arrows B. Thus it will be seen that the disintegrated coal, and other products will become thoroughly impregnated with said solution and steam before it falls to the bottom of the chamber 35, or before it commences its travel along the partition or bottom 18. Fire being located upon the grate 27 will necessarily heat this partition or bottom 18, and as the disintegrated coal, &c., is carried by the endless carrier along said partition or bottom 18,it will become thoroughly dried by the time it reaches the discharge spout 32.

It may be here stated that the endless carrier moves at approximately a low rate of speed.

Any gases, foul air, &c., arising in the chamber 35 will be discharged through the pipe 31 and into the flue 30.

The smoke and products of combustion from the fire located upon the grate 27 will be discharged through the aperture 29 and smoke stack of flue 30.

Should lignite be disintegrated and discharged through the chute 34, the valve 54 should be closed, thereby cutting off the supply of the solution from the tank 61 and the valve 63 opened. Thus it will be seen brine, or a like solution will be discharged through the T-shaped casting 48 together with the steam, and thoroughly impregnate the lignite.

A correct solution of brine, 850., causes ordinary lignite'to assume the same properties as ordinary coal. Consequently said lignite can be very satisfactorily used.

In the modified form shown in Fig. 4, disintegrated coal, lignite, &c., is dried by passing over the bottom or partition 72 located within the chamber 74, in which is held superheated steam, &c.

Thus it will be seen how I have formed a simple, efficient and easily operated drier for disintegrated coal, lignite, &c.

What I claim is- 1. A heater for disintegrated coal, 850., comprising a rectangular box like structure composed of two or more sections, a bottom or partition located within said box like structure, an endless carrier running immediately above this bottom or partition, a T--shaped casting enteringthe forward end of this box like structure immediately above the endless carrier and connected to pipes which lead. to tanks, and a nozzle for forming a steam-jet, substantially as shown and described.
